I posted another post about kids and rollercoasters and someone had mentioned that if they are close in height then sometimes they'll be turned away for not being tall enough. My daughter is exactly 40 in. right now (40 1/2 in. with her shoes on!). Do you think I'll run into any problems with her going on the coasters? I'm hoping maybe she'll gain another 1/2 in. between now and early oct. but I doubt it!
